ChatGPT picks Nvidia over SpaceX for Q4 2026 investment
OpenAI’s ChatGPT has chosen Nvidia (NASDAQ: NVDA) as the better stock to buy in Q4 2026, favoring it over SpaceX (NASDAQ: SPCX). The model cited Nvidia’s dominance in artificial intelligence and its strong risk-reward potential for investors.
Nvidia’s investment case is backed by solid financial performance, not just future projections. The company reported $96.2 billion in quarterly revenue in August, with $89 billion coming from its data center segment. This growth is driven by increasing demand for AI infrastructure from cloud providers, enterprises, and governments. Nvidia also benefits from its role in AI inference, a key growth area as AI applications move from development to real-world use. The company’s Blackwell platform and upcoming Rubin architecture further strengthen its position.
While Nvidia was the preferred pick, ChatGPT acknowledged SpaceX’s potential for long-term upside. SpaceX’s businesses include Starlink, Starship, launch services, defense contracts, and AI-related infrastructure. Recent milestones, such as Starship’s orbital mission and Starlink’s expansion to 10 million subscribers, support the company’s ambitious goals. If successful, Starship could drastically reduce launch costs and reshape the space industry.
Despite SpaceX’s promise, ChatGPT concluded that Nvidia offers more certainty heading into Q4 2026. Nvidia’s growth is already reflected in its earnings and expanding AI market share, while SpaceX’s future value hinges on Starship’s success and regulatory approvals. For investors seeking exposure to both, ChatGPT suggested a hypothetical allocation of 70% Nvidia and 30% SpaceX.
